Dating app Bumble filed a lawsuit Wednesday against Match Group, which owns dating platforms like OkCupid, Match and Tinder, asking for $400 million in damages.

The suit alleges that while looking to buy Bumble, Match Group gathered information on the company and then filed a lawsuit for patent infringement.

"Match tried to poison Bumble in the investment market," according to Bumble's filing, and "wrongfully disparage the Bumble platform."

In a statement Thursday, Match Group called the lawsuit petulant and meritless.

"Last week, Bumble claimed our complaint was baseless and won't affect them, and this week they claim it is 'chilling' the sale of their company," the statement said. "We obviously think their lawsuit has no substance."

In 2014, Bumble CEO Whitney Wolfe Herd sued Tinder, alleging sexual harassment and discrimination during her time working there at the app's beginning.
